如何在C / C ++中执行no-op？ [英] How does one execute a no-op in C/C++?

问题描述

代表以下内容：

( a != b ) ? cout<<"not equal" : cout<<"equal";

假设我不在乎它是否相等，我如何使用上面的语句替换<$

suppose I don't care if it's equal, how can I use the above statement by substituting cout<<"equal" with a no-op.

推荐答案

如果它真的是一个三元运算符，不需要第二个动作，最好的选择是替换为一个if：

If it really is for a ternary operator that doesn't need a second action, the best option would be to replace it for an if:

if (a!=b) cout << "not equal";

它会闻到很少。
